and retain the rregistry ofthat inclination.`

A further object of the invention is the production of an inclinometer having, in its normal adjustment, spirit level glasses of substantially the usual and ordinary type, which vill register both level and plumb in the usual manner. v

A further object of the invention is to provide an inclinometer in which the spirit n levels, fixed at an angle of 90o, are carried by a movable part,\which moves under inanual control to some inclination other than vlevel and plumb, and remains in such assumed position until manually returned to normal, or to another inclination. '20' A further object of the invention is to provide the moving part V'with a table of figures which shall coact. with a pointer, so that the inclination assumed by said moving part m shall indicate, from the chart reading, the

use to be made from the registered inclination.

A further object of the invention is to pro* vide the necessary mechanical parts to carry j forward the above objects. f

, functional equivalents thereof as will be hereinafter more fully described and claimed.

In the drawings, Fig. 1 is a view of the invention in side in fragment.

Fig. 2 is a view of the operating parts of the inclino-meter in side elevation, with the outer protecting plate and glass removed.

Fig. il is a vView in side elevation of the outer protecting plate.

Fig. 5 is a view in side elevation of the band or frame which is mounted within the stock and carries all of the operative parts.

Fig. 6 is a view in side elevation of the 'responding' the circular channel 22. elevation associated with a level stock shown movablejpart, which will be 'hereinafter referred toas the, disk. f j l Fig. 7 is an enlarged vdetail view ofthemanual control. v l Y i Like vcharacters of Vreference indicate col- 55A `parts throughout the several views.

The improved' inclinometer which forms the subject matter of 'thefapplicatiom' coinprises a stock, similarto'the usual and 'ordi- 60 naryfspirit level stock," and serving everyv function of such a spirit levelzinthe manner to be herein more fully set forth. Y

rlhe stock 10, is provided Aats'ome position within its length, preferably centrally, 'with 65 a cut out portion extending entirely'through the stock, and therefore, opening upon both lateral sides. Within this cutout a frame 11 is positioned, saidlframe 11 being in the l vpintel 15, is a clip 16, rigidly attachedto the disk 17, all oscillatingupon the pintel 15.`

Oscillation is'imparted to tlieparts manually by,v providing thev clip 16, with` an arcuate 90 rack 18, engaged by a sliding rack 19, which extends parallel with the bar 12, ,and out wardly through the frame' 11, provided 'with a screw-threaded portion 20, with a iknu'rled nut21, mounted to rotate in 'the frame V11, but held against longitudinal movement by -When the diskis in Contact with the adjusting screw`v27, which screw also supplements the loo screw 14, in maintaining the 'frame in position.

The frame carries a pointer 28, which indi- Cates upon the disk 17 certain graduations 29, upon the disk, having` proper leads to a chart 30. The chart as shown indicates generally a framing chart, but it is to be understood that the invention is in no way limited to any specilic chart, or to any chart at all, and the chart is only indicated to suggest a utility for the device.

The disk 17 is provided with an edge 31 which will serve as a stop to limit the movement of the disk to an amplitude of from normal.

` The whole working part is covered and protected by plates 32 inset into the stock and provided with slots 33 for the knurled nut 21 so that the said nut shall be accessible from without the plates. Between each plate and the edge of the frame 11 is positioned a sheet of a transparent medium 33, which may be glass or some less fragile material.

In operation with the parts assembled as shown at 1, the device serves in all respects as a level, as usually employed by mechanics. When, however, it is desirable to ascertain the inclination of a given body the nut 21 is manipulated until one or the other of the level glasses indicates level in the usual manner, and the inclination may then be read by the position of the graduations relative to the pointer 28. If the requirement is framing, for example, the exact framing cut may be ascertained'from the chart. It some other chart is employed for some other purpose, the utility will be at once apparent.

I claim:

1. A registering inclinometer comprising a stock, means in said stock having a semicircular opening therein with its straight side parallel to one side of said stock, a circular sector element'pivoted in said means at the center of said semicircular opening, means located in the plane of said stock and parallel to one side thereof for manually adjusting the position of said sector, and a pair of leveling units mounted on said sector at right angles to each other.

2. A registering inclinometer comprising a stock, means in said stock having a semicircular opening therein 'with its straight side parallel to one side of said stock, a `circular sector element pivoted in said means at the center of said semicircular opening, means located in the plane of said stock and parallel to one side thereof for manually adjusting the position of said sector, and a pair of leveling units mounted on said sector at right angles to each other, said sector' having a table of graduations thereon, and a pointer carried by said stock and cooperating with the Said graduations,

3. A registering inclinometer comprising` a stock, an open semicircular frame mounted ried by said sector and mounted at right i angles to each other and means mounted in said frame and within the plane of the stock for adjusting the position of the sector with' respect to the stock.

In testimony whereof I aflix my signature.
